About

Building a chip takes hundreds of engineers and years of work. Physical design — the placement, routing, and timing of transistors — is one of the hardest stages: thousands of interdependent decisions, sparse domain data, and no general-purpose AI that understands circuit structure. This role exists to change that.

This is an early-stage startup backed by top EU investors, building an AI reasoning system for physical chip design. The analogy is closer to OpenAI's math reasoning work: teaching a model to navigate symbolic, graph-structured problems from first principles.

You'd be the first AI hire, working directly alongside the co‑founding team and a founding chip design architect. You’d have the opportunity to grow into Head of AI as the company scales post‑seed.

What you’ll do

  • Design and build AI reasoning systems that understand circuit structure and make design decisions autonomously
  • Build post‑training pipelines — fine‑tuning, reward modelling, and feedback‑driven learning on proprietary chip design data
  • Develop synthetic data generation strategies for a domain with limited open‑source examples
  • Drive data strategy, model architecture, and inference optimisation across the full AI system
  • Work directly with the founding chip design architect to understand problem structure and translate it into training signals
  • Shape technical direction alongside the founders — framing problems, proposing approaches, designing experiments

What you’ll need

  • Deep, hands‑on experience building AI systems for hard, novel problem domains — reasoning, mathematics, biology, physics, or similar
  • Ability to build reasoning models from scratch: post‑training, fine‑tuning, data strategy — not just deploying existing pipelines
  • Strong fundamentals across model architecture, training dynamics, and inference optimisation
  • First‑principles mindset: given a new structured problem, you can understand it and build an AI system to solve it
  • Startup mindset: comfortable with ambiguity, able to move fast without a large team behind you

Optional Bonus

  • Experience with symbolic reasoning, graph-structured data, or formal methods
  • Background in post‑training for reasoning or maths‑style models
  • Synthetic data generation for low‑data domains
